UNITED STATES EMORY PARSONS, OF NEWARK, NEW JERSEY.

TIME LIGHTING DEVICE;

Application filed October 17, 1922. Serial No. 595,049.

To all whom it may concern Be it known that I, EMORY PARSONS, a citizen of the United States, residing at 304: Montclair Avenue, Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Time LightingDevices.

My invention relates to improvements in a time lighting device; the objects of the improvement are, first, to provide the means for closing a circuit over which electrical energy may flow, at a predetermined time, and during the absence of the attendant, second, to provide means to indicate the time at which the circuit closing portion of the device will operate. My invention may be usedin service in which electric power, or

illuminating electric lights, or signal electric lights, is or, arerequired to becomeoperative at a time when no attendant is present, but it is designed primarily for use in closing, during the absence of the driver, the electric light circuit which controls the standing, or parking, lights ordinarily found on motor driven vehicles.

My inventionis illustrated in the accom panying drawing, in which Figure 1 is a view of such parts of the device as are essential to an understanding of the fol1owing description ofit; Figure 2 is a front view of the indicator hand and dial; Figure 3 is a plan view of the lever contact, the threaded part of the driving shaft and the guide arm;

Figure 4 shows a sectional view of the device hereinbefore more particularly described in which the ratchet, 5, and the spring, 4:, are detailed.

In Figure 1, 1 is a shaft, called the driving shaft, such as is found in an ordinary clock but with the addition of a threaded extension, the shaft being shown without supports for the purpose of leaving the drawing more clear, 2 is a gear wheel attached to shaft 1 in such position that it will operate a train of gears, also omitted for the purpose of leaving the drawing more clear, but indicated by the broken lines, connected with gear wheel 13 which drives the shaft on which indicator hand 14 is mounted in such position that it will move over the dial 15 as gear wheel 13 is rotated, a front view of the indicator hand and dial being shown in Figure 2, 3 is a second gear wheel loosely mounted on shaft 1 so that the shaft may be rotated in one direction without moving the wheel but equipped with a ratchet 5, the pawl of which will drag as shaft 1 is rotated in one direction and will lock with and nove the gear wheel 3 when the shaft 1 is rotated in the opposite direction, 1 is a coil spring, one end of which is fastened to shaft 1 and the other end to the housing of the device, 6 is the threaded part of shaft 1, 7 is a guide arm with loops to be fitted over shaft 1 at the ends of thread 6 and set at such distance from the threads 6, between the loops, as will allow free movement of lever contact 8 as the threads, by the rotation of shaft 1, force lever contact 8 back or forward, towards or away from the position shown by the dotted line 8, 9 is the point at which lever contact 8 is pivoted to its support and to which one wire of an electric circuitis to be connected, 10 is a contact point'into which lever contact 8 is to enter and to which the second wire of an electric circuit is to be connected, 11 is a shaft to which is attached two gear wheels, one of which is set in such position that it will be operated on by a train of gears, omitted for the sake of clearness, put in motion by gear wheel 3 as ratchet 5 locks it to shaft 1 when shaft 1 is rotated in the proper direction, the second gear wheel on shaft 11 being con nected to an escapement, shown for brevity in the form of a triangle.

In Figure 3, 7 is the guide arm with loops around the shaft, 8 is the free end of the contact lever which moves forward or back as threads 6 are rotated, threads of a large size being shown for clearness.

From the foregoing description it can be seen that as shaft 1 is rotated by a key adapted for that purpose indicator hand 14 will operate by the action of the train of gear wheels and that lever contact 8 will operate by the action of threads 6 and that a proper adjustment of indicator hand 14 will cause it to pass over or leave the zero mark on dial 15 at the very moment lever contact 8 leaves contact point 10 and that as lever contact 8 is forced further from contact 10 by threads 6, indicator hand 14: will be forced to pass over the points on dial 15 marked 5, 10, 15 etc. and that as shaft 1 is rotated coil spring t will be wound.

It can also be seen that when the winding force applied to shaft 1 is released, coil spring 4 will exert its recoil strength on shaft 1 and cause it to rotate in a direction opposite from that in which it was rotated by the "force also force lever contact 8 to moye away from the position indicated by the dottdlnf 8" towards, and into, contact point 105 the speed of shaft 1, While bein'g driven by the @011; pri nd ll me m nt t ll d by.
